Instrument for Stimulating or Irritating And/or Abrasively Treating And/or Polishing a Membrane or Surface or Inner Surface in the Human or Animal Eye

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention is a mechanical surgical instrument designed for use in ophthalmology, particularly for stimulating, irritating, abrasively treating, or polishing membranes or surfaces inside the human or animal eye. It consists of a handle with an actuating element and a probe containing a thin loop that can be extended out of or retracted into the probe during eye surgery. The device enables minimally traumatic manipulation of delicate eye tissues, such as during preparation and implantation procedures for conditions like age-related macular degeneration.

Use CasesContent extracted from patent full text and abstract with AI.

• Preparation and insertion of subretinal implants, especially in treatments for age-related macular degeneration (AMD).
• Atraumatic removal of the retinal pigment epithelium (RPE) layer in the eye.
• Epiretinal membrane peeling and other retinal surgeries requiring precise tissue manipulation.
• Polishing the inner surface of the lens capsule or treating scars within the eye.
• General stimulation or irritation of ocular membranes to facilitate healing or transplantation.

BenefitsContent extracted from patent full text and abstract with AI.

• Minimally invasive and gentle handling of delicate eye tissues, reducing the risk of damage compared to conventional abrasive tools.
• Enables precise, controlled, and safe removal or polishing of membranes within the eye, minimizing trauma to surrounding structures.
• Simple, mechanical design for cost-effective manufacturing and easy sterilization or single-use implementation.
• Reduces complications such as scarring, unwanted cell damage, and traumatic injuries during ophthalmic surgery.
• Adaptable for different surgical requirements by modifying loop material, size, or surface.
• Improved surgeon control through ergonomic handle and actuating mechanism, with features like pressure equalization and adjustable angles for better access.

Patent Abstract

The invention relates to an instrument for stimulating or irritating and/or abrasively treating and/or polishing a membrane or surface or inner surface in the human or animal eye, comprising a handle (1), which comprises an actuating element (2), and a probe (3), which adjoins the handle (1) and which is open at the free distal end, for introducing into the eye. The invention is characterized in that the probe (3) comprises a loop (4) in the interior, and the loop can be at least slightly pushed out of the probe (3) and pushed or pulled back into the probe (3) by means of the actuating element (2).
